OpenOffice.org Base is No Microsoft Access Replacement
OpenOffice.org Base is a desktop database application that may be used to perform the standard tasks of creating and manipulating tables, queries, forms and reports.
Base is well integrated with the rest of the OpenOffice.org suite—for instance, data sources that live in Base are easy to pull into mail merge documents in Writer—but the feature parity and format support gaps between Base and Microsoft’s Access make this part of OpenOffice.org less well suited as a drop-in replacement than are the suite's other components.
Base, which recently underwent a 3.0 version bump alongside the rest of OpenOffice.org, corresponds roughly to Access, but the gap between Base and Access is broader than those between the two suites' other rival applications. OpenOffice.org 3.0 was released Oct. 13.
Most importantly, the support that Base offers for Access database files is much more limited than what the rest of OpenOffice.org provides for its Office counterparts.
